My car is going into the dealership tonight for this issue. This will be the second time. I have been trying to do some self trouble shooting. It was fixed the last time untill the maintenance update occured. Now at 4:00 pm my time the calendar catches up. That means the caledar is 16 hours behind. It has something to do with the am and pm setting on the clock. I will update you more after I get my car back from the dealership. Keep your fingers crossed for me.
